What was the original purpose of shaking hands? Peace signaling.

The original purpose of shaking hands lies in ancient rituals of peace and alliance, a gesture that has endured for millennia. Understanding this history reveals why the handshake remains a powerful symbol of trust today. Discover how this simple act evolved from a signal of deactivated weapons to a global greeting.

The Weapon Check: Proof of Peaceful Intentions

The original purpose of shaking hands was a practical safety protocol designed to prove that both parties were unarmed and had no ill intentions. In ancient times, where survival often depended on a healthy dose of suspicion, the gesture allowed strangers to physically demonstrate they werent concealing a dagger or a blade in their hand. It was less about politeness and more about ensuring you wouldnt be stabbed in the middle of a greeting.

This need for safety led to the specific up-and-down motion we still use today. The physical shaking was intended to dislodge any hidden weapons - specifically knives or daggers - that might be tucked away in a sleeve. If someone was hiding a blade, the vigorous movement would likely cause it to fall out. It was a primitive but effective security check. Simple. Brutal. Effective.

Lets be honest, the idea of shaking a hand to dislodge a dagger sounds like a scene from an action movie. I used to think this was just a tall tale until I actually tried hiding a pen up my sleeve during an etiquette workshop. It takes a surprising amount of force to shake something loose, which explains why ancient handshakes were often quite vigorous. If you didnt shake hard, you werent showing trust; you were being suspicious.

Ancient Roots: From Greek Vases to Assyrian Kings

While many think of the handshake as a modern business tool, its archaeological footprint stretches back thousands of years. Stone reliefs and Greek vases from 5th-century B.C.E. show soldiers and gods clasping hands to signify a bond of peace or a sacred oath. These early depictions suggest the gesture was already well-established as a symbol of agreement and mutual respect long before the rise of modern diplomacy.

Even earlier evidence exists in the form of an Assyrian relief dating to the 9th century B.C.E. This artifact shows King Shalmaneser III shaking hands with a Babylonian ruler to seal an alliance. The gesture appears consistently across Mediterranean and Middle Eastern cultures, maintaining its identity as a symbol of agreement and peaceful intent between parties.

In Rome, the gesture evolved into something even more secure: the forearm grab. By grasping the opponents forearm rather than just the palm, both parties could feel for weapons hidden in the folds of a tunic or sleeve. This was the enhanced security version of the greeting. It makes you wonder (and I certainly have while watching historical dramas) how awkward those moments must have been when someone actually felt a weapon during the grab. The greeting would turn into a combat situation in a heartbeat.

The Quaker Influence: Equality in the Palm of Your Hand

The transition from a military safety check to a common social greeting happened much later, largely driven by the Religious Society of Friends - better known as the Quakers - in the 17th century. Before this era, greetings were heavily stratified. You bowed to your betters, tipped your hat to your peers, and acknowledged your inferiors with a nod. The Quakers found these hierarchical displays to be inconsistent with their belief in the equality of all people.

They popularized the handshake specifically because it was an egalitarian gesture. Since both people are at the same level and performing the same action, no one is superior. This was a radical social shift. By the mid-1800s, this Quaker greeting had become the standard across much of the Western world, replacing the more formal and submissive gestures of the past. It turns out that a simple hand clasp was one of the most effective tools for dismantling social barriers.

The Science of the Handshake: Why We Still Do It

Today, we arent usually checking for daggers (at least, I hope not), but the handshake remains a powerful psychological tool. Touching another persons palm triggers a chemical reaction in the brain. Specifically, it releases oxytocin - often called the bonding hormone - which naturally fosters a sense of trust and connection. In business negotiations, research indicates that parties who start with a handshake are significantly more likely to reach a mutually beneficial agreement.

The impact is measurable. Studies in behavioral psychology show that a firm handshake can increase the likelihood of a successful interaction compared to a verbal-only greeting. ^[3] It anchors the conversation in a physical reality. When we touch hands, we are essentially telling our prehistoric brains that this person is a friend rather than a threat. But theres a catch. A weak or dead fish handshake can actually have the opposite effect, signaling a lack of confidence or trustworthiness.

Ill be honest: Ive had meetings where the initial handshake was so limp it felt like holding a cold noodle. It immediately made me feel uneasy. Even knowing the science behind it, that gut reaction is hard to ignore. It took me years to realize that my own handshake was part of the problem. I was so worried about being too aggressive that I wasnt providing enough pressure to trigger that trust response in others. Finding that balance is a skill in itself.

Evolution of the Greeting: Ancient vs. Modern

While the physical act of clasping hands has remained stable, the intentions and variations of the gesture have shifted dramatically over the centuries.

Ancient Handshake

• Military alliances or meeting strangers on the road
• Vigorous shaking to dislodge hidden blades
• Safety and weapon detection

Roman Forearm Grab

• Loyalty between soldiers or political allies
• Firm grip on the forearm to check for weapons hidden in the folds of a tunic or sleeve
• Enhanced security check

Modern Business Handshake

• Professional meetings, deals, and social introductions
• Moderate pressure with 2-3 pumps
• Building rapport and signaling trust

The Power of the First Grip: David's Lesson

David, a junior account manager at a firm in London, struggled for six months to close his first major contract. He was technically brilliant but often felt a distance between himself and potential clients during initial meetings.

During a review, his mentor noticed David's greeting: he would offer a tentative, sweaty palm and quickly withdraw it. The friction was palpable; clients felt his nervousness as a lack of competence, causing them to hesitate on every proposal.

The breakthrough came when David learned the history of the handshake. He realized it wasn't just a formality but a way to signal safety. He began focusing on a dry, firm grip with steady eye contact, mimicking the 'egalitarian' approach of the Quakers.

Within 30 days, David closed a deal worth 45,000 USD. He reported that the 'atmosphere' of his meetings changed instantly, leading to a 40% increase in client follow-up rates by the end of the quarter.

Cultural Adaptation in Hanoi: Mai's Discovery

Mai, a project coordinator in Hanoi, was working with a European delegation for the first time in 2026. She was used to a gentle, respectful nod and was initially overwhelmed by the assertive handshaking of her foreign counterparts.

She tried to mirror their intensity but felt awkward, often gripping too hard or mistiming the shake. This mismatch in 'greeting energy' created an underlying tension that made the first two days of negotiations stall.

She realized that a successful handshake isn't about power, but about synchronization. She adjusted her approach to wait for the other person's lead before matching their pressure, turning the gesture into a shared rhythm.

The result was a significant thaw in relations. The lead negotiator later noted that the team felt much more 'at home' once the greetings became natural, helping the project launch two weeks ahead of schedule.
